Hey folks, I've tested compatibility of this tool with my mainboard today.

Boardname: ASRock TRX40 Creator

Vendor website: http://www.asrock.com/mb/AMD/TRX40%20Creator/#Specification

Flash-chip: Winbond 25Q128FWSQ - 16MB

SuperI/O: nuvoTon NCT6683D-T

For the folks interested - A webpage with amazingly detailed photos of that mainboard, including chips and whatnot:

Note that this page is currently down for me, but you can still access it via the wayback machine.

Commands ran:

sudo flashrom/flashrom -r biosdump.bin -p internal

# Note that TRX4CTR1.70 is the rom file that's freely downloadable from ASRock's website.

binwalk -W -i TRX4CTR1.70 biosdump.bin > binwalk_diff.txt

# Since I'm not really fond of firmware file layouts yet, somebody who's smarter than me might want to verify whether

# the differences are mainly due to different bios configs and hardware I've added into my system,

# or if some firmware section got omitted on read.

more binwalk_diff.txt | grep 0x0 | wc -l

# This command showed '17430'. Since binwalk shows 16 bytes per line, there should be about 34kb of differences in binary.

# Flashed back the official rom, since I don't really trust the read one.

sudo flashrom/flashrom -p internal -w TRX4CTR1.70

# The output from that is in the attached file.

sudo flashrom/flashrom -p internal -V
